Enter any two dates and this calculator returns the gap between them broken down into years, months and days, rather than just a single total-day figure, which makes it easier to read at a glance for things like relationship anniversaries, project durations or age gaps between siblings.
A full day count is shown alongside the broken-down figure for anyone who needs the raw number rather than the readable version — useful for legal or contractual purposes where a precise day count matters. Either date can be in the past or future, and the order doesn't need to be chronological.
